Description
The SM89516B series product is an 8 - bit single chip
micro controller with 64KB flash & 1KB SRAM
embedded.
SM89516B is a versatile and cost effective controller
for those applications which demand up to 36 I/O pins,
or applications which need up to 64K byte flash
memory either for program or for data or mixed.
To program the on-chip flash memory, a commercial
writer is available to do it in parallel programming
method.
